Facebook themes and skins
• This style was built to work properly with the Facebook's new design (here: https://www.facebook.com/about/newsfeed, if you're lucky, I'll get this design soon xD). For classic version, use this: Facebook's New Design + (for classic version)
• I don't recomend installing this if you're using the "classic" version of Facebook (it will work, but some stuff might be broken).
• Also, I don't recomend installing this style in slow computers or old browsers, it uses lots of css transitions, which is kinda a heavy work for some slow computers.
Basically, this style adds a few graphical features to Facebook, including rounded pictures (which turns squared on mouseover), transitions, the top bar always follows your scroll, no matter in which part of Facebook you are (without this style, for an example, in your profile page the top bar doesn't scrolls with the screen), and uh...that all :).
To use this style, first install Stylish.
(Though installing Stylish is recommended, TamperMonkey users can also install this style as a user script.)
